Hypothalamusb. Hypo-pituitaryc. Thalamus V. Brain StemCurrent Lecture1. Video: Capgras Delusion- Traumatic brain injury resulted in some of the axons connected to the amygdala broken. This leads the guy to not be able to recognize objects and faces. Can’t evoke proper emotional response to it. Had delusions about people. When you look at object message goes to temporal lobe, but you don’t respond to object emotionally because it doesn’t go to amygdala. Separate pathway from auditory to amygdala (talks to dad on phone and knows its him)2. Video: Temporal Lobe Epilepsy (TLE)- excess emotion, feels the same about a paper clip as he does to his daughter. Extreme high and low emotions follow seizures. Kulver-Bucy SyndromeThese notes represent a detailed interpretation of the professor’s lecture. GradeBuddy is best used as a supplement to your own notes, not as a substitute.- Bilateral temporalimbic lesion- Behavior changeso Hyperoralityo Hypersexualityo Changes in aggressive behavioro Visual agnosiao Indiscriminate orienting and exploration Diencephalon (other part of Forebrain)- Hypothalamuso Switch board, determines which hormones the pituitary glands will release into blood streamo Hypo and thalamus work as a unit- Hypo-pituitaryo Fight or flight- stress/cortisol (amygdala)o Feeding- metabolic homeostasis, balancing energy demands, intake vs outtake, fluids, electrolyte balances (THC binds to receptors in hypothalamus and blocks these signals because neurotransmitters are being repressed)o Sexual behavior- - Thalamus o The brain’s relay centero Touch, pain, incoming signals go to thalamus before they route it to the correct cortex Brain Stem (midbrain and hindbrain form the brain stem)-Superior colliculus and Inferior colliculuso Auditory, reflexes -Reticular formation-Substantia nigra- Periaqueductal Grey (PAG)o Behavioral responses to threatening and sexually arousing stimulio Electrical stimulation in humans dreado Descending inhibition of pain (DI) Brains morphine-like and THC-like
